To all whom it may concern:

Be it known that I, MicHAEL PARIDON, a citizen of the United States, and resident of Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Mechanisms for Stacking Cartons and the Like, of which the following is a specification.

This invention relates to a machine for stacking cartons or other boxes, and it has for its object to provide a. simple and eflicient construction and organization of mechanism whereby boxes are successively arranged one partially within another, or nested, so as to occupy comparatively small compass for convenience of packing and transportation.

The invention has been especially, though not exclusively, designed for use in connection with or as an attachment to machines for making the cartons in which bookmatches are packed, whereby the said cartons as rapidly as they are discharged from the machine are intercepted and compactly assembled.

The invention, broadly considered, comprises the combination with means for feeding boxes, of means for receiving the boxes and disposing them successively in oppositely-inclined relation to each other, whereby one end of each box is caused to enter into and be nested in an inclined position in the immediately preceding box in such a manner that the successive boxes are stacked in staggered or zig-zag formation.

More specifically, the invention comprises the combination with a carrier for supporting a succession of boxes, bottoms downward, and feeding them successively to a point of discharge, and a vertically-reciprocating plunger for discharging the boxes successively from said carrier, of a receiver into which the boxes are successively delivered as rapidly as they are discharged from the carrier, and means for effecting a relative reciprocatory movement between the receiver and the path of each of the successively delivered boxes, whereby the angularity of each uppermost box in the receiver is varied in respect to that of the next suc- Fig. 2 is a perspective view of the stacking receiver, detached.

Fig 3 is a vertical section of a portion of said receiver and the associated box e ector, showing the latter in discharging position and illustrating the relative positions of a stack of boxes within the receiver;

Fig. is a transverse vertical section, as on the line 44 of Fig. 1.

Fig. 5 is a detail view, showing the cams and the actuating gearing therefor.

Fig. 6 is a perspective view of a box. Referring to the drawings,'10 designates several of the open former links of the endless chain of a well-known type of boxmaking machine, which links are intermittently impelled in the usual manner to the path of a vertically-reciprocating ejector 11, whereby ineach dwell of the chain a box is discharged from one of the links through an opening 12 in a table 13 which is supported by a standard 14 on the supporting frame work. My invention in its broad aspect contemplates the use of any other approved type of box-making machine, or any other suitable source of box supply.

The form of ejector illustrated comprises a yielding frame of inverted V-form supported by a vertically-reciprocative crosshead 15 which is mounted on vertical guide posts 16 on the table. This cross-head is connected by means of a link 17 to one arm of a rock-lever 18 which is fulcrumed on a standard 19 on the supporting frame. The other arm of the lever is connected by means of a link 20 with one arm of a lower rocklever 21 which is also fulcrumed on the standard 19; the other arm of lever 21 bearing a roller 22 which enters the run of a suitably-disposed face cam 23. This cam is fast on a drive shaft 24 having its bearings in suitable standards, including the standard 1 1, on the main frame, whereby during the operation of said shaft the cam in its rotation effects, through the described lever and link connections, the timely reciprocation of the ejector in respect to each succeeding link of the box chain.

Directly under and communicable with the discharge opening of the table 13 is a box receiver, comprising in its preferred form a vertically-disposed casing 25, open at top and bottom, into which the boxes (B) are successively delivered by the ejector. This casing is of appropriate internal form and dimensions for the reception and guidance of the boxes therein. It is substantially equal in width to a box so that the boxes delivered thereto are slidingly held in place by the frictional contact of their sides with the proximate walls of the casing. The interior length (horizontally) of the casing slightly exceeds the length of a box, so as to compensate for the alternately projecting ends of succeeding boxes when the boxes are arranged one within the other, as below described; the mouth of the casing being outwardly flared, as at 26, to afford ample space for the free delivery of the boxes thereto.

The lower portion of the casing is conveniently pivoted on a stud 27 affixed to the supporting frame. so that the casing may be swun alternately to right and left oblique positions, and thus correspondingly incline the contained boxes. Each an lar position of the receiver is effected just efore the introduction of a box thereto by the ejector, that is to say, the receiver is swung to one inclined position before the introduction of a box thereto, and then to the other inclined position before the'introduction of the next succeeding box, and so on. When the receiver is swung to the left hand side (as illustrated in Figs. 3 and 4) the uppermost box therein is correspondingly shifted, thus positioning the left-hand end Wall of such box out of the path of the overlying end corner of the descending box from the box machine, and permitting such corner to enter the mouth of the underlvinbox while the opposite end of such descending box'impinges against the ri ht-hand end of the underlying box. When the receiver .is swung to the right, the box last previously entered thereinto is swung to the right with its right-hand end wall out of the path of the overlying end corner of the next descending box from the box machine, thus permitting such overlying corner to enter the mouth of the underlying box, and the opposite end of the descending box to bear upon the right-hand end of the underlying box. In this way, in each oblique position of the receiver, a box is introduced thereto and partially entered into the immediately preceding box in the receiver; the series of boxes thus nested in oppositelv-inclined or zig-zag order, as clearly seen in Fig. 3 being progressively depressed as each box is delivered to the receiver.

Any appropriate means for shifting the receiver in timely relation to the reciprocatlons of the ejector may be employed. The

means herein illustrated includes an approtends an anti-friction roller 29 on the adjacent side of the receiver. This cam is fast on a shaft 30 having its bearing in the standard 14, said shaft being driven from the shaft 24 through meshing gear wheels 31, 32 on the respective shafts. The ratio of the gearing is such that the cam 23 makes. two rotations during one of the cam 28, and the relative contours of the two cams are such that in each rotation of the shaft 24 the ejector is reciprocated by the .cam 23 and the receiver is shifted either to the right or to the left by the action of the cam 28.

The boxes stacked in the receiver as aboveexplained are delivered therefrom into the upwardly-curved end 33 of a horizontal chute or trough 34 which is suitably supported at or adjacent the lower end 'of the receiver. Predetermined quantities of the assembled boxes may be readily removed from the trough by an attendant and orated.

1 preferably arrange above the curved end of the trough an overhanging curved spring 35 which bears yieldinglv upon the opposing ends of the assembled boxes as they are diverted from a vertical to a horizontal path and thus prevents their accidental separation or displacement.

It is to be understood that my invention is not limited to the structural features herein illustrated, asthe mechanism may be variously modified within the scope of the appended claims.

I claim 1. The combination of a box-receiving element constructed to support a stack of open mouth empty boxes, one partially within the other, in staggered order of succession, a box-dehvering element for entering successive boxes, bottoms foremost, into the said 1 receiving element, one of said elements being mounted for to and fro movement transversely of and within the path of travel of the succeeding boxes to the receiving element, and means for shifting said movable element from one of its limits of movement priate face cam 28 into the run of which exto the other after the entry of each succeeding box into the said box-receiving element. 2. The combination of a movable boxreceiving element constructed to support a stack of o en-mouth empty boxes, one partially within the other, in staggered order of succession, a box-delivering element for en 'tering successive boxes, bottoms foremost,

into the said recelvlng element, and means receiving element constructed to support a cally reciprocative member for introducing stack of open-mouth empty boxes, one partially within the other, in staggered order of succession, a reciprocative element for entering successive boxes, bottoms foremost, into the said receiving element, means for reciprocating the said entering element toward and from the receiving element, and meansfor reciprocating said meceiving element transversely of andwithin the path of travel thereto of the succeeding boxes, each transverse movement of said receiving element being eflected after the entry therein of each succeeding box.

4. The combination of a vertical box-receiver, a pivotal support therefor, a vertically "reciprocating member for introducing boxes to the upper end of said receiver, means, for oscillating said receiver, and means for reciprocating said member at the end of each movement of the receiver.

5. The combination of a vertical box-receiver, ajpivotal support therefor, a vertiboxes -to the upper end of said receiver, means, including a cam, for oscillating said receiver, and means, including a cam, for reciprocating said member, said cams being so relatively formed and actuated that the said member is reciprocated at the end of each movement of the receiver.

6. The combination of' a vertical box-receiver, a vertically reciprocative member for introducing boxes to the upper end of the receiver, means for periodically shifting the receiver from one position to another in respect to the path of said member, means for actuating said member in each position of the receiver, a chute having a curved portion extending from the lower end of the receiver, and a pressure member overhanging such curved portion.

7. The combination with a carrier for supporting a succession of individual boxes, bottoms downward, and feeding them successively to a point of discharge, and means for discharging the successive boxes down- Wardly from the carrier, of a movable boxreceiving, element into the upper end of which boxes are successively delivered, said receiver being constructed to support a stack of said boxes, one partially within the other, in staggered order of succession, and means for moving said receiving element to and fro transversely of and within the path of travel of the succeeding boxes as they are discharged from the said carrier, each transverse movement of said receiving element being eifected after the entry therein of each succeeding box.
